NASA scientists have found that many nearby asteroids have the potential to strike the earth:

(Reuters) – About 1,000 asteroids big enough to cause catastrophic damage if they hit Earth are orbiting relatively nearby, a NASA survey shows…An asteroid or comet between 5 and 10 km (3.1 and 6.2 miles) in diameter is believed to have smashed into Earth some 65 million years ago…So far, there is no plan about what to do if an asteroid was discovered to be on a collision course with Earth.http://www.reuters.com/article/2011/12/07/us-space-asteroids-idUSTRE7B615O20111207

Over 1900 years ago, notice what the Apostle John was inspired to write in the Book of Revelation 8:10-11:

Then the third angel sounded: And a great star fell from heaven, burning like a torch, and it fell on a third of the rivers and on the springs of water. The name of the star is Wormwood. A third of the waters became wormwood, and many men died from the water, because it was made bitter.

A large comet hitting the earth would also seem to have similar effects to that of a medium-sized asteroid. And having something actually hit the earth and do massive damage is predicted in the Bible. Of course, since NASA was referring to asteroids, so its comments should mainly be considered as indirect confirmation.

Although the biblical Wormwood does not have to be a comet, it sounds more like one than an asteroid.

Why?

In addition to looking like a star falling from the heavens looking like a torch (and an asteroid could possibly do that), comets normally appear with cyanogen. Astronomers state hydrogen cyanide on comets may be their source of cyanogen gas.

Interestingly, the cyanogen gas mixes with water to form hydrogen cyanide, which has an almond odor and bitter taste, and reportedly causes death at concentrations over 5 parts per million.

And thus for Bible skeptics, the fact that before humans had any idea that comets could produce a poisonous bitter water, it is recorded in the Bible. This should be additional proof to those willing to see that the Bible has been inspired by God.

And while comets are still more likely to fulfill the Wormwood prophecy than asteroids, humans still have no real effective way to deal with potential asteroid devastation, and some day, a major object from the sky will strike the earth according to biblical prophecy.

NASA scientists now know that at least 1,000 nearby asteroids could do that, and have long known that certain comets could do this as well.
